Scope of this to investigate the steam-gasification in
solar assisted gasification reactor of three types of lignite coal that
produced in Turkey
was investigated. In this gasification process, heat was supplied from solar
energy. Using of solar energy as process heat, the discharge of pollutants is
avoided, the gaseous products are not contaminated by combustion products and the calorific value of the fuel
is upgraded [1].
Turkey is a rich country in terms of
reserve of lignite coal. But these lignite coal reserves have got high ash,
humidity and sulphur rates and low calorific value of fuel. From this view, it
is necessary to use these coals with gasification for avoiding the discharge of
pollutants and upgrading the calorific value of the fuel. Furthermore, these
coals are most appropriate fuel type because, they allow sensitive combustion,
doesn’t leaves waste materials such as slag, ash, etc allows high combustion
temperatures [2].
In this study, exergy and
irreversibility calculations which are related coal type of reactor, heat
exchanger and quencher are carried out from data obtained from literature and
given as tables. Finally,
the exergetic efficiency expressions for different coal types are obtained.
